The maximum stable baud rate for softserial is 19200.
ESP8266 uses the default baud rate of 115200 after reset.
To use ESP with softserial you must set the default baud rate for ESP using USB-TTL converter. Send AT command AT+UART_DEF=19200,8,1,0,0
Check that the ESP sets the required baud rate after reset

thank you
as knowing i need to define baudrate 9600 or 19200 because the default 115200
the new firmware make me choose between baudrate's but did not work on remotexy

I am just going through this exercise and I have had some troubles, but I have made progress.
To use softserial at say 19200bps, you must also set the baudrate in the ESP8266 to 19200. It will probabaly default to 115200.
I used a second USB-RS232 (TTL) module to momitor the soft serial ports & this was a problem.
Solution.
Make a direct connection to the USB-serial dongle to ESp8266 and use AT command to change the baud ratei
ie. AT+UART_DEF=19200,8,1,0,0

I could then see the communication between Arduino & 8266
AT
AT+RST
ATE0
AT+CWMODE=2
AT+CWDHCP=0,1
AT+CWSAP="RemoteXY","",10,0
AT+CIPMODE=0
AT+CIPMUX=1
AT+CIPSERVER=1,6377
AT+CIPSTO=7
And doing it again & monitoring the corresponding responses
OK
OK
OK
OK
OK
OK
OK
OK

I could then see the AP ok and I could connect to it. However, at the connection, it did not send any data and came up with a message

Error device does not reply using iPhone
Error Device not reply. Receive time out error. using Android

I did capture some data from the esp8266 back to arduino
+IPD,0,6:U��
+IPD,0,4:�
+IPD,0,6:U��
+IPD,0,6:U��0,CLOSED
Nothing is sent from the arduino to the 8266

SO that is where I am stuck at present.

im trying to send message to my laptop from my smart phone across arduino uno
the problem is the laptop connect with arduino via usb (hard serial)
and my esp8266 connect with arduino with softserial connection
my phone dose'nt find the wifi to show the interface of app
any one help ??
